Haha, I find this shirt amazing.  I use ‘nandeyanen’ ALL THE TIME in American.  Some of my cashiers will notice me saying it and be all like “what the hell?”.  Basically it means “you have to be kidding me” and you can say it when someone says something ridiculous.  Like if one of my cashiers asks for an additional break.  I picked up the habit at Nagano High School and just fell in love with the word.  It’s amazing.  This shirt is amazing.  I’m probably going to buy it.

Second is this “urusai” shirt.  Urusai is a little tricky to translate because its dynamic and can change meanings in different situations.  It can be used to insult someone or to tell someone to shut up.  Either way it means they’re being loud and obnoxious.  In ESS club sometimes the leaders would yell that out to people if they were talking.  Haha.  Japanese high schoolers.

Both are from http://www.gesshoku.org/ which has some pretty interesting tshirt designs.  Stumbled on the site totally on accident (thanks Google) but some of their stuff just cracked me up because of personal memories.
